Welcome to the PSR Tutorial Forum, DallasW!
If you have deleted all the settings (Registrations) saved on the Reg buttons 1 - 8 (in the REGISTRATION EDIT display) so that none of the reg buttons are lit, you can no longer call up any settings using the Reg buttons. (Refer to the S970 Reference Manual, page 83.)

OTS LINK" function. Then when you switch the Style Main Variations A - D, the "associated" OTS (One Touch Setting) is automatically loaded (Main A > OTS 1, Main B > OTS 2, etc.).
Note: When using
Registrations, the "
OTS LINK" button should always be switched
OFF. If necessary, you can of course call up the 4 OTS (on buttons 1 - 4) manually at any time. However, any previously activated Reg button is then deactivated, since the OTS settings are then loaded.
If your problem persists, please contact us again here. Then describe your previous approach in more detail.
Best regards,
Chris
